This species is assessed as Endangered due to an expected population decline over more than 50% in the past and the future inferred from the extensive and rapid habitat loss.

Geographic Range [top]

Range Description:This species has been recorded from southern Thailand, Peninsular Malaysia (from Selangor and Pahang, to Johore) including the island of Penang (Medway 1983). It also occurs in Sumatra and Borneo (including Kalimantan, Sabah, Sarawak and Brunei Darussalam) (Thorington et al. 2012).
Countries occurrence:
Brunei Darussalam; Indonesia (Kalimantan, Sumatera); Malaysia (Peninsular Malaysia, Sabah, Sarawak); Thailand

Upper elevation limit (metres):3000

Population [top]

Population:According to Bornean and Malay records it is probably a rare species as it is rarely seen even in primary forest. Even in optimum habitat it is not abundant. There are probably two relatively secure populations (with not large numbers) in Mt. Kinabalu National Park (Sabah) and in a nearby protected area.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This nocturnal species lives in tree hollows in tall, undisturbed lowland primary forest (below 3,000 m asl), but it also relies on exposed nests. It is less common at higher elevations but a few populations have been found on the island of Borneo. Peak breeding occurs between April to June but this species does breed throughout the year, producing one or two young. Nest holes were recorded at Poring which were three to four metres above the ground in trees (Jackson 2012). Females have an average pregnancy rate of 9 percent over a three-year period (Thorington et al. 2012).
Generation Length (years):3.7

Use and Trade [top]

Use and Trade: There is no information on use and trade available for this species.

Threats [top]

Major Threat(s): This species is likely to be affected by habitat degradation because of its low elevational range.

Conservation Actions [top]

Conservation Actions: Parts of its range are contained within well-managed, good condition National Parks.
